My experience with planning my wedding and large corporate dinners is that caterers need a general idea of the numbers and an exact figure 72 hours before the event. The only stipulation is that there is not a big difference in the numbers. If you guarentee 250 2 weeks before, there is no problem saying the exact number is 245 72 hours out and only paying for 245. You would probably be stuck paying for the larger amount if you tried to say 200 instead of 250 though.

That being said, unless there is a major illness, death or some other true emergency, I think it is rude to cancel a wedding at this late date. The Bride is probably already stressed, and canceling not only means another call to the caterer, but possibly changes in seating charts and other things that could be a big headache. I would say go and then leave after dinner at the reception.
